Re: Cam advice
The thing that stands out to me with that overall combo is....... it has way less stall than I’d use.
Somewhat handy with a die grinder.

The thing that stands out to me is that it doesn’t look like a 650hp combination. If it is, you are a sharper dude than I am.
Re: Cam advice
That cam will peak HP around 7,000rpm, and would like more stall(4,500-4,800)

Re: Cam advice
So an 8" converter would be in order. I know this is not a 650hp combo. If this made 500, I would be perfectly happy. I was not trying to win engine masters. What about this camshaft? How would the two act differently? I have typically ran narrow LSA in the few Fords I have dealt with. Would the 110 with this cam do alright?

Re: Cam advice
This cam would move peak power up to about 7,400rpm, and need a 5,000 stall

Re: Cam advice
I think he was refering to a 650 cfm HP style Holley carb not that it will make 650 hp . Dannovafornow wrote: ↑Tue Jul 14, 2020 11:06 am The thing that stands out to me is that it doesn’t look like a 650hp combination. If it is, you are a sharper dude than I am.

Re: Cam advice
4.86 gear , more stall, 750hp carb =10 second ETs . my similar 331 does but with a 5.29 gear and 8,000 in the lights.
Re: Cam advice
Camking,
The second camshaft, the Manufacturer said RPM Range: 3000-7500, the first cam was RPM Range: 4200-7200 which you were pretty much spot on with your analysis. That was why I asked what the second cam would do. Myself thinking, this is more duration and a wider LSA, how will this make the power range lower. You said just what I thought...peak power went up. So that cam in the car probably would make a slower et. In your opinion, would you go smaller yet or is the 1st cam a decent choice if I would up the stall speed? This engine will not get shifted higher the 7000 most likely, probably 6500/6800 range.

Re: Cam advice
If you're not going to turn it over 7,000rpm, this is what I would recommend
Cam#, F351w, R73400-74406-106
247/251 @.050"
.400"/.406" Lobe Lift
106 LSA
This would also work well with your current stall speed/

Re: Cam advice
Can you give a guess at the HP this combo will make Mike?
